Industrial SD Memory Cards

Industrial SD Memory Cards

The Delkin Industrial SD Memory Card is a reliable NAND flash storage solution for industrial applications that utilizes the Secure Digital interface.  Delkin offers industrial-grade high endurance SLC NAND flash SD card solutions in the D300,and D200 Series, and Commercial cost-effective MLC NAND flash versions in the Utility and Utility+ Series.  Every Delkin Industrial SD card features a controlled Bill of Materials (BOM) and strictly adheres to the specifications set forth by the Secure Digital Association.

While SD cards primarily began in 1999 as a storage medium for consumer electronics, key characteristics such as small size, low power consumption, high reliability, and simplicity of integration also make the form factor an ideal fit for many industrial applications with limited real estate for storage.

Industrial SD Speed Classes & Bus Interface

Delkin Industrial SD Memory cards are classified as Normal Speed, High Speed, or Ultra High Speed (UHS-I or UHS-II). These classifications are differentiated by the Bus Speed of each card, with indicates the maximum theoretical read and write speed capability. Similarly, each card has a speed class that is designated by the SD Association, which is based on the minimum sequential write speed that the card performs at. While theoretical speeds can be quite high, actual card speeds are usually lower and vary by card configuration, the operation being performed, how the data on the card is organized, and the host device.
